White Rice Postulated to Increase Diabetes Risk

http://www.bmj.com/content/344/bmj.e1454

A meta-analysis finds increased risk for type 2 diabetes with high consumption of white rice. A comment in BMJ cautions against major dietary changes, however. (A brief interview with the senior author is available through the Clinical Conversations link below.)


Researchers examined the association between white rice consumption and diabetes risk in four observational studies comprising some 350,000 subjects; two thirds were from Western countries. Participants were free of self-reported diabetes at baseline and were followed for 4 to 22 years.


In comparisons between subjects in the highest and lowest consumption categories, the relative risk for diabetes was roughly 1.3 overall. Asian populations showed a significantly higher risk (1.55), whereas Western populations — with consumption levels roughly one fifth that of Asians — showed a 1.12 relative risk. The authors speculate that white rice's reduced nutrient content may play a role in the increased risk, in addition to its glycemic load.


An editorialist comments that the findings "cannot support large scale action."

很久以前就有鎘米事件了...

鎘米與痛痛病　

日前農委會藥物毒物試驗所發現，雲林虎尾有兩處農地稻米含鎘(Cadmium)量超過食品衛生標準，也就是說，長出了鎘米，引起了社會大眾的恐慌。但是，很多人仍然不懂，鎘米是什麼？有那麼可怕嗎？

鎘米是新品種的改良米嗎？不是！，它是指由受重金屬‘鎘’所污染的農地長出來的稻米，這些稻米含鎘量過高，吃入人體之後，會累積在人體，引起一些難癒的病痛。最糟糕的是，它的半衰期長達10-30年！

至於，為什麼重金屬鎘會跑到農地裡？鎘經常用來作鎳鎘電池、染料、塗料色素及塑膠製程中的穩定劑。這些工廠所排出的廢水若未經妥善處理，而逕行排入灌溉渠道，就會使農地受到鎘的污染。這些鎘經農作物吸收，就長出鎘米，鎘菜、鎘水果了。

被鎘污染的農作物，吃進人體後，大量的鎘會沈積在肝及腎，而引起貧血、肝功能異常及腎小管功能受損。腎小管的功能受損後會使較小分子的蛋白質及鈣由尿中流失，長期下期就會引發軟骨症(osteomalacia)、自發性骨折(pseudofracture)及全身到處疼痛，這就是所謂的痛痛病(Itai-Itai disease)。

鎘中毒後沒有解毒劑，沒有任何有效的根治方法，只能針對病痛的症狀給予支持性、治標性的治療。患者的痛苦可是一輩子無法解脫的！所以，農委會及環保署的官員們要加油，加強防制重金屬對環境的污染；相關廠商要有良心，不要任意排放含重金屬的廢水；農民們也要拿出良心，不該把含鎘的稻米藏起來或是惡意出售吧？至於一般老百姓們，只好祈禱上蒼---不要讓我們吃到鎘米吧！
